When a steam system shuts down, the remaining steam condenses into water, which takes up a much smaller volume than the original steam. This creates a vacuum, which can damage equipment if not relieved of in a timely way. Vacuums prevent gravity draining systems from working properly, which can lead to frozen condensate and burst piping.
Vacuum Breakers are simple, reliable devices that provide a positive means to automatically relieve or “break” an unwanted vacuum condition.
Available in sizes from 1/8” up to 4” NPT.
⅜” & ¾” NPT is also available with field adjustable range from ¼” to 20” (8 – 508mm) Hg Vacuum for use on closed vessels and piping systems to control induced vacuum within safe limits.
